Performance analysis of asynchronous band-limited DS-CDMA systems in generalized-K fading with multitone jamming

2007 6th International Conference on Information, Communications & Signal Processing, 2007
Bit-error-rate (BER) analysis of an asynchronous band-limited direct-sequence code-division multiple-access (DS-CDMA) system in the presence of multitone jamming (MTJ), multiple-access interference (MAI) and additive white Gaussian noise (AWGN) is presented in this paper.

A new anti-jam receiver for MFSK/FFH system with multitone jamming

2008 11th IEEE Singapore International Conference on Communication Systems, 2008
In this paper, a differential jamming rejection (DJR) receiver in fast frequency hopping (FFH) M-ary frequency shift keying (MFSK) systems with a worst-case band multitone jamming (MTJ) is introduced. This receiver, based on detecting frequency spectrum difference in forward-backward time slot while the FFH/MFSK signal arrive receiver, implements ...

Multitone jamming of FH/BFSK in Rician channels

IEEE Transactions on Communications, 1999
A new bit error rate (BER) expression for a noncoherent frequency-hopped binary-frequency-shift-keying (FH/BFSK) receiver in Rician channels, subjected to independent multitone and wideband noise interference, is derived. Unlike previously published analyzes, we combine the signal and jammer multipath components, the additive white Gaussian noise (AWGN)

Performance of Differential Frequency Hopping System under Multitone Jamming

2006 Asia-Pacific Conference on Communications, 2006
Differential Frequency Hopping (DFH) is a novel technique for the frequency-hopping system in HF (High Frequency) bands. The frequency transition function (FTF) and the signal detection methods are the key issues for DFH system. Symbol-by-symbol detection and sequence detection are adopted in DFH system.

Performance analysis of an FFH/BFSK self-normalising receiver under multitone jamming

IEE Proceedings - Communications, 1998
Analytical expressions for bit-error probability are derived for a fast frequency-hopping binary frequency-shift-keying (FFH/BFSK) spread-spectrum (SS) communication system based on Taylor-series expansion. The FFH system employs a soft-decision self-normalising receiver against the worst-case multitone jamming (MTJ) and additive white Gaussian noise ...

Performance study of a maximum-likelihood receiver for FFH/BFSK systems with multitone jamming

IEEE Transactions on Communications, 1999
We derive the optimum structure of a maximum-likelihood (ML) receiver for a fast frequency-hopped binary frequency-shift-keying (FFH/BFSK) spread-spectrum (SS) communication system operating in the presence of multitone jamming (MTJ) and additive white Gaussian noise (AWGN). It is shown that the side information of noise variance, signal tone amplitude,
